If it's not a "large impact", what is the fuss about? I suppose if the effect exists at all it would be intellectually interesting and all but so are many other things. I thought the point of dwelling on this work was the claim that more than half of 20th C warming could be attributed to this effect. This is extremely implausible under Ockham's Razor; you need to explain why the sun is acting up just now, why on exactly the time scale and in the expected range of amplitude of the greenhouse forcing, why the expected greenhouse effect is not working as expected, why the cosmic ray forcing is somehow concentrating at high latitudes (very peculiar, that) and so on. It was very very much a long shot even before Sloan and Wolfendale showed that it could not possibly account for the majority of the change. ( http://www.iop.org/EJ/article/1748-9326/3/2/024001/erl8_2_024001.html ) Why bring it up now? There are plenty of real issues to talk about without dwelling on the endless supply of red herrings. It will be very difficult to get an alternative theory with comparable explanatory power to the one we already have. Why? Well, sometimes, you know, science actually gets results. mt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
